Answer 1

You can store your history in some array and do some manipulation with last/previous items.

var history = [];
this.listenTo(this, 'route', function (name, args) {
  history.push({
    name : name,
    args : args,
    fragment : Backbone.history.fragment
  });
  console.log(history);
});
